"I learned Test and Balance (TAB) the old-school way—working as a TAB helper for one of the biggest NEBB-certified companies in the Greater Cincinnati area. So when I launched HVAC 2 Home Performance in 2015, I knew TAB would be part of what we offered. In 2016, I took the National Comfort Institute’s Light Commercial TAB certification course—and that’s where I met Scott Fielder. Scott has forgotten more about TAB than most people will ever know. He quickly became both a mentor and a great friend. The man has never missed a call or failed to call me back within an hour. That kind of support is rare. Fast forward to 2024—Scott is now repping the most innovative TAB equipment company on the market: Evergreen Telemetry. Like many in the field, I cut my teeth on Big Red and used plenty of Big Blue too. And when hoods got smarter, I bought one of those. But nothing compares to the level of thought and ingenuity Evergreen brings to making a TAB tech’s life easier. It’s not just the gear—it’s the people. Scott’s a TAB rockstar who knows this equipment inside and out. Tori can walk you through every technical detail and clearly explain the value to people like I once was—on the fence but curious. Even their admin and accounting folks are top-notch. Real pros. Real humans. And Evergreen believes in what they build. They’ll even send you a full set for a free trial—because they know you won’t want to give it back. We work in both residential and light commercial, and Evergreen's versatility is unmatched. The 2x2 and linear setups are anything but traditional—lightweight, grid-mountable with magnets, and that slick BT digital wrist readout? Game changer. Then there’s their 8" low-flow hood, which rivals powered flow hoods for accuracy and handles residential and light commercial exhaust like a champ. If you're serious about delivering accurate, efficient, and professional TAB work, Evergreen Telemetry isn’t just a good choice—it’s the only choice I’d make. "
